It functions as an input coupler with an integrated relay: the 24 V AC/DC coil drives one change-over contact rated for 6 A thermal current. The 6.2 mm width is the main space-saving feature — it packs a relay and isolation into a slice narrower than most terminal blocks, so it fits densely on a DIN rail inside a control panel. The hard gold-plated contacts suit low-level switching (e.g., PLC inputs, signal-level loads) where standard silver contacts might oxidize and fail to close reliably. RoHS compliant since 26 September 2024. REACH Article 33 information is available under the current candidate list.","metaTitle":"Siemens 3RQ4038-2AB01 SIRIUS 3RQ4 Coupling Relay, 24 V AC/DC","metaDescription":"Siemens 3RQ4038-2AB01 SIRIUS 3RQ4 coupling relay.
